SPECIFICATION forming part of Letters Patent No. 718,844, dated January 20, 1903.

Application filed September 13, 1902. Serial No. 123,297. (No model.)

To all zui'tont it may concern.-

Be it known that I, ARTHUR RICHARD HUS- KISSON, a subject of the King of Great Britain, residing at 72 Glenfield street, Blackley, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Gasements, of which the following is a specification.

This invention relates to easements and has been devised with the principal object of enabling both sides of the glass in the folding leaf of a casement-window to be cleaned and of permitting repairs, painting, and the like to be done from within the room.

I will describe my improvements with reference to the accompanying drawings, in which- Figure 1 shows an inside elevation, and Fig. 2 a section along the line a: 50, Fig. 1. Fig. 3 shows a section corresponding with Fig. 2, but with the folding leaf of the easement opened. Fig. at is again a corresponding section showing the folding leaf reversed for cleaning the outside surface of the glass. Fig. 5 is a partial horizontal section showing details of the catch construction. Fig. 6 is a sectional elevation showing the sliding pin on the inside of the folding leaf. Fig. 7 is an elevation of the slide-link stud on the outside of the folding leaf. Fig. 8 is a side elevation; Fig. 9, an end elevation of the bolt for securing the inner and outer frames of the folding leaf together, and Fig. 10 a sectional elevation of the clamping device for the slide-link.

For the purpose of my invention 1 construct the folding leaf with a duplex framethat is to say, with an inner frame I), in which the glass 0 is fixed, and with an outer frame cl, hinged or pivoted to the easementframe a. The top and bottom rails d of the outer frame extend to about the middle of the easement, where they are connected to the inner frame I) by the hinges ff. The outer frame (1 of the folding leaf is hinged or pivoted at g to the casement-frame, and, as shown in detail by Figs. 8 and O, the contiguous vertical members of the frames 6 d can be secured together or liberated by a bolt and catches. The bolt h is capable of sliding vertically on the inner surface of theframe (Z, on

which it is guided and held by two set-screws t, passing through slots made in the frame, into the bolt. The bolt is notched atjj to engage two correspondinglyshaped projections jj, formed or secured upon the contiguous face of theinner frame I). At about the center of the bolt there is a projection therefrom through a vertical slot in the frame d, to which there is pinned the swing-handle 7.5, which has a hole formed through it near the bottom and a slotted or forked end By means of a projection Z the bolt can be firmly held in the open or in the closed position by moving the bolt upward or downward and en gaging it with the projection. As shown in said Figs. 8 and 9, the bolt is closed and the hole in the swing-handle is engaged by the projection Z. \Vhen the inner frame is to be liberated and put into the position shown by Fig. 4, the swing-handle is released, the bolt is pushed upward, and the swing-handle is again folded down, but this time with its forked end engaging with the projection l, by which the bolt is held 1n the open position. If the slide-link m be now released from the folding leaf, the latter can be turned right around upon the hinges ff, so as to present its outer face toward the inside of the room, as shown by Fig. 4, in which position the outside of the glass can be easily and comfortably cleaned by a person standing inside the room.

For the purpose of holding the folding leaf in its normal open position, Fig. 3, or in the reversed open position, Fig. 4:, there are fixed on opposite sides of the leaf the sliding pin 0 and the slide-link stud n, with either of which the link may be engaged. The sliding pin 0 is shown drawn to a larger scale by Fig. 6 for general use inside the leaf and the slidelink stud n by Fig. 7 for use outside the leaf. The sliding pin 0, Fig. 6, is cylindrical and can be moved upward or downward in the boss n by means of a suitable head formed on its upper end. In the side of the sliding pin there is a vertical slot with horizontal branches, one only of which is shown, in which engages the point of a screw passed through the side of the boss 'n. Thereby the sliding pin is prevented from being removed entirely from the boss with the risk of loss. The boss n is horiby Fig. 5.

zontally slotted for the admission of the perforated end of the slide-link m, sothat when it is required to liberate the slide-link it is only necessary to lift the sliding pin 0, giving it a slight turn to the right or left to secure it in that position and withdraw the end of the link from the boss 71.. The slide-link stud n, Fig. 7, is cylindrical and is part of a bracket, by which it can be attached to the frame.

The slide-link m can be clamped in any position in which it may be placed by rotating a nut 19 downward upon a vertical screw fixed to the bracket q'and passing through the longitudinal slot shown in the slide-link, Fig. 10. By loosening the nut 10 sufficient angular motion is permitted to enable the link to be lifted over the stud n.

It is important that the folding leaf should be held firmly closed by means of its fastener and so that the fastening shall not be accidentally loosened, and I attain this object by means of a spring-catch such as is illustrated or to a projection therefrom, carries a screwed stud fitted with the nut s. The catch t is pivoted upon the stud between the nut and the plate, and the pivot-hole therein is recessed for the reception of a spiral spring to. A washer is interposed between the nut and the spiral spring, and the inner face of the nut is turned down to enter the recess, as shown, so that When the nut is screwed home the spring becomes compressed upon the bottom of the recess in the catch, and the latter is thus firmly but yieldingly held in. any position in which it may be placed.

A plate 7", fixed to the inner frame slide-link stud on the outside of the inner frame, a slide-link capable of being connected with either the sliding pin or the slide-link stud, and a catch for holding the folding leaf in the closed position, substantially as set forth.

2. In a casement, a fixed frame, a folding frame hinged to the fixed frame, an inner frame hinged to the folding frame and containing the glass, and a bolt connection between the folding and inner frames which together constitute the folding leaf, constructed substantially as and for the purpose set forth.

3. In a casement, a reversible folding leaf, a sliding pin on the inside and a slide-link stud on opposite sides thereof, a slide-link capable of being connected with either the sliding pin or the slide-link stud, and a fixed clamping device for the slide-link, substan tially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

A. R. HUSKISSON.
